The Untouched Omega (The Shifters of New York #2)
Alex DuBois
It's war. In a dangerous world where shifter battles the military, a newly-mated pair of wolves must face their joint fate together, even while fate conspires to separate them. While danger reigns around Dante and his inexperienced omega, the draw of heat is impossible for any fated mates to resist.
But Dante is the key to infiltrating the military faction that threatens all of shifter kind, and a soon pregnant Cory must do his best to help from afar. Will their efforts be enough to secure a safe future for their growing wolf pup?
The Untouched Omega is a MM mpreg story, and it features explicit scenes, fated mates, and love conquering all. It can be read as a standalone, though the characters featured in it do appear in other Alex DuBois books.
